Resolve 12 Beta 3 crashing importing C300 clips

I am having trouble importing C300 clips in Resolve 12b3. When I navigate to the camera card on my RAID, I can only load one "CLIPS001" folder with 10 clips, and when I try to import one of those clips, I get an immediate crash. If I drag the camera subfolders directly into Resolve it's fine. Also, there should be 10 folders of clips (23 in all) and not just 10 clips. Oddly, one of our other suites running almost the identical set-up (MacPro, UltraStudio 4K, Resolve 12b3) had no issues, and showed 10 folders and all 23 clips imported fine. Not sure if some of clips are spanned...

Anyway, here's what I have tried so far:
- Uninstalled and re-installed Resolve
- Created a new user
- Created a new database on a different volume

Frankly, dragging the clips into Resolve is a fine workaround, but clearly there's an issue navigating to the files within the media tab.
